BACKGROUND

Living in a fast-paced modern society, many people, especially young office workers, regularly forget to drink the water due to their busy work. Inadequate water consumption can lead to health problems. Currently, a wide variety of smart water bottle or thermal bottle products have been launched on the market, and these products are usually provided with a built-in function module for statistics of water consumption and reminding the user to drink water. However, the addition of the functional module on the water bottle or the thermal bottle often renders the structure of the bottle more complex and increases the volume of the bottle, which is very inconvenient to use. Moreover, there is a high possibility for water bottles or thermal bottles to come into contact with water and to suffer fall-off or hitting during use. Therefore, it is necessary to develop a product which not only can remind users to drink water, but also has a simpler structure, lighter weight, and better waterproof performance, and can withstand frequent fall-off or hitting, etc. Furthermore, existing water bottles with the function of monitoring the user's water consumption generally measures the amount of water in the bottle and calculates the water consumption through the changes of the amount of water.

EMBODIMENT

Referring to FIGS. 1-3 and 9, according to one aspect, the present disclosure provides a smart water bottle holder 100 including a bottle holder main body 10 for accommodating a bottle and a control unit 20 provided in a bottom part of the bottle holder main body 10. The control unit 20 includes a weighing module 21, for Obtaining a total weight of the bottle and water therein; a controller 22, for determining whether a user performs a water thinking action according to movement data, wherein if the user performs the water drinking action, after the bottle is put down and stands still, the controller 22 controls the weighing module 21 to weigh the bottle and water to obtain a current weight, and calculate a difference between a previous weight and the current weight as a water consumption, otherwise, the controller 22 controls the weighing module 21 to weigh the bottle and water to obtain and save the current weight after the bottle is put down and stands still; a communication module 23, for sending water consumption data to an external terminal; and a power module 24, for supplying power to the weighing module 21, controller 22, and communication module 23. As an implementation of the present disclosure, the controller 22 may be a control chip such as a micro control unit (MCU) etc., which can send the water consumption data to various external smart terminals, such as smart phones, IPADs and other devices. The communication module 23 may be a functional module capable of wireless and/or wired connection for signal transmissions; such as a BLUETOOTH module or a WIFI module. Further, the controller 22 may also detect the capacity and charging status of the power module 24, and convert the battery capacity data into percentage type. The battery capacity percentage, water consumption, and charging status are sent to the corresponding APP installed in the smart terminal through the communication module 23.

As an implementation of the present disclosure, the controller 22 is further used to determine whether the standstill time of the bottle is greater than or equal to the threshold, if yes, entering a sleep mode. The control unit 22 further includes a wake-up module 25 for detecting a movement signal of the bottle holder main body 10, and the wake-up module 25 is further used for issuing a wake-up signal when the movement signal is detected. The controller 22 is further used for acquiring the movement data of the bottle holder main body 10 according to the wake-up signal, and determining whether the bottle holder main body 10 is put down and stands still, if yes, a timer is started. The controller 22 is further used for determining whether a standstill time of the bottle holder main body 10 is greater than or equal to a threshold, if yes, entering a sleep mode. Furthermore, the wake-up module 25 is a multi-axis accelerometer, and the multi-axis accelerometer is configured to obtain the movement signal of the bottle holder main body 10. For example, the wake-up module 25 may be a three-axis accelerometer used to obtain the three-axis output of the bottle holder main body 10, The three-axis accelerometer can be set to issue the wake-up signal when the output of one axis, two axes, or three axes of the three-axis accelerometer is/are greater than or equal to a predetermined threshold. The issuance of the wake-up signal may be achieved by setting the wake-up function of the accelerometer. When the output of any one, two, or three axes of the accelerometer is greater than or equal a preset acceleration threshold, a pin of the accelerometer is paused to output a pause signal to wake up the system.

As an implementation of the present disclosure, the controller 22 is further configured to obtain outputs of the multi-axis accelerometer at a fixed frequency according to the wake-up signal, create a curve of the outputs within a period of time, analyze parameters of the curve, and recognize the drinking action, wherein the parameters of the curve include a shape of the curve and a slope of a key point of the curve, etc. For example, the controller 22 may obtain the outputs of the multi-axis accelerometer at a frequency of 10-60 times/sec, and create a curve within a time period of 1 minute, then recognize whether the user performs the water drinking action by analyzing the shape of the curve and the slope of the key points of the curve. Specifically, when the user drinks water, the action is relatively gentle and, roughly at a uniform speed, so the multi-axis acceleration of the bottle is kept at a low level or even close to 0, and the curve of the outputs of the multi-axis accelerometer is relatively stable. Whereas, when the user is pouring water or shaking the bottle, the action is generally strong and quick, and the change of accelerations is more obvious than the action of drinking water. Therefore, different actions can be recognized according to the shape of the acceleration curve or the slope at key points of the curve, and the action of drinking water can be identified.

As an implementation of the present disclosure, as shown in the logic block diagram of FIG. 11, the multi-axis accelerometer may be set to wake up the system when the output of any one of the multi-axis is greater than the wake-up threshold when the bottle is picked up. Then, the controller 22 acquires the data of the multi-axis accelerometer (i.e. the movement data) and determines whether the bottle is put down and stands still (the system can determine whether the bottle is put down and stands still by judging whether the output of the accelerometer is 0). If yes, a timer is started and the weighing module 21 is controlled to weigh the bottle and water therein to obtain and record a current weight as w_(t). Otherwise, the acquisition is continued to obtain the movement data of the bottle holder main body. The controller 22 further creates a curve based on the outputs of the multi-axis accelerometer and determines whether the user performs the water drinking action. If the user performs the drinking action, a difference between a previous weight w_(t) and a current weight w_(t) is calculated as the water consumption, then the value of w_(t)is replaced with the value of w_(t). otherwise, the value of w_(t-1) is replaced with the value of w_(t) directly. Then, the controller 22 determines whether the standstill time of the bottle is greater than or equal to the threshold, if yes, entering the sleep mode, otherwise, returning to the step of weighing the bottle and water therein to obtain and record a current weight as w_(t). Further, the controller 22 creates a curve based on the outputs of the multi-axis accelerometer and determines whether the user performs the water drinking action, and then performs operations such as entering sleep mode, etc.

As an implementation of the present disclosure, preferably, the smart bottle holder can be applied to water bottles with a capacity of 1000cc or 2000cc etc., or the user can set a daily target water consumption according to his/her own needs. First, the user needs to fill the bottle with the water of the desired amount, then firmly connect the bottom of the bottle to the smart bottle holder and put it down to standstill. Afterward, the system of the smart bottle holder is initialized and started to obtain the weight of the bottle and water therein as the basis for calculating the weight difference when the weight is obtained again the next time. The water consumption data can be cleared and updated every day. Further, a target water consumption for a fixed time period per day can be set. If the target water consumption is not reached in the corresponding time period, a reminder may be sent through the communication module 23 to the external smart terminal to remind the user to drink water.

As an implementation of the present disclosure, the bottle holder main body 10 includes a first cavity 11 and a second cavity 12 that are separated from each other. The bottom of the bottle is detachably connected to the first cavity 11, and the control unit 20 is arranged in the second cavity 12. Optionally, as shown in the figures, the bottle holder main body 10 may further include a detachable lower cover 30 for sealing the second cavity 12. The bottle holder main body 10 may also not include the lower cover 30, namely, the second cavity 12 is directly sealed during molding. The first cavity 11 is detachably connected around the bottom of the bottle, so the smart bottle holder of the present disclosure can be applied to various water bottles, thermal bottles and other products to realize the function of water consumption statistics and reminding users to drink water in time without the need to reconstruct the structure of the bottle body. Hence, the smart bottle holder of the present disclosure has stronger structural mobility and wider range of applications. In addition, since the space for accommodating the bottle is separated from the space for accommodating the control unit, the waterproof performance and the safety of use are improved, which prolongs the service life.

As an implementation of the present disclosure, the weighing module 21 includes several weighing sensors 211, and the weighing sensors 211 are evenly arranged around the bottom of the bottle. For example, as shown in the figures, the weighing sensors 211 may be evenly arranged to surround the bottom side of the bottle 100 at the front, rear, left, and right sides of the bottle bottom as shown in the drawing. The even arrangement of the weighing sensors 211 around the bottom side of the bottle can solve the problem of an unbalanced load of the sensors caused by a single point of force when only one sensor is provided, and reduce the overall volume of the weighing module 21. Further, the weighing sensors 211 may be pressure sensors or other sensors that can obtain the weight or water consumption data. The first cavity 11 may be made of a silicon material, and the second cavity 12 may be made of a silicone material or other materials, such as plastic and the like. The first cavity 11 and the second cavity 12 may also be integrally formed without joint lines, which improves the visual effect and waterproof performance. Further, the control unit 20 may also upgrade the device firmware over-the-air, aka. OTA. The power module 24 may be charged by magnetic wireless charging, and the lower cover 30 may be configured as the surface to be coupled with the wireless charger. When the lower cover 30 is successfully coupled with the wireless charger, the power supply module 24 would get charged.

As an implementation of the present disclosure, the controller 22 may be a control chip such as a micro control unit (MCU) etc., which can send the water consumption data to various external smart terminals, such as smart phones, iPADs and other devices. The communication module 23 may be a functional module capable of wireless and/or wired connection for signal transmissions, such as a BLUETOOTH module or a WWI module. Further, the controller 22 may also detect the capacity and charging status of the power module 24, and convert the battery capacity data into percentage type. The battery capacity percentage, water consumption, and charging status are sent to the corresponding APP installed in the smart terminal through the communication module 23.

As an implementation of the present disclosure, the controller 22 is further used to determine whether the standstill time of the bottle is greater than or equal to the threshold, if yes, entering a sleep mode. The control unit 22 further includes a wake-up module 25 for detecting the movement signal of the bottle holder main body 10, and the wake-up module 25 is further used for issuing a wake-up signal when the movement signal is detected. The controller 22 is further used for acquiring movement data of the bottle holder main body 10 according to the wake-up signal, and determining whether the bottle holder main body 10 is put down and stands still, if yes, a timer is started. The controller 22 is further used for determining whether a standstill time of the bottle holder main body 10 is greater than or equal to a threshold, if yes, entering a sleep mode. Furthermore, the wake-up module 25 is a multi-axis accelerometer, and the multi-axis accelerometer is configured to obtain the movement signal of the bottle holder main body 10. For example, the wake-up module 25 may be a three-axis accelerometer used to obtain the three-axis output of the bottle holder main body 10. The three-axis accelerometer can be set to issue the wake-up signal when the output of one axis, two axes, or three axes of the three-axis accelerometer is/are greater than or equal to a predetermined threshold. The issuance of the wake-up signal may be achieved by setting the wake-up function of the accelerometer. When the output of any one, two, or three axes of the accelerometer is greater than or equal to a preset acceleration threshold, a pin of the accelerometer is paused to output a pause signal to wake up the system.

The weighing module 21, the controller 22, communication module 23, power module 24, and wake-up module 25 are arranged and laminated in the second cavity 12. The weighing module 21 is located close to the partition of the first cavity 11 and the second cavity 12, This arrangement can greatly reduce the volume of the electrical modules, the lamination of components can reduce the displacement of the components during movements and improve the fall-off and hitting resistance, and the weighing module 21 being located close to partition of the first cavity 11 and the second cavity 12 can improve the sensitivity of the weighing sensors.

An engagement protrusion is provided on the edge of the upper surface of the bottom cover 204. A groove for engaging with the engagement protrusion is provided on the edge of the lower surface of the middle plate 203. Further, the upper surface of the middle plate 203 is provided with sensor mounting regions 205 for placing the weighing sensors 202 in a one-to-one correspondence. The sensor mounting regions 205 and the weighing sensors 202 are the same in number. Sensor pressing members 206 are further provided to press and reinforce the sensors from the edges. Pressing protrusions 207 are provided on the lower surface of upper cover 201 at the positions corresponding to the weighing sensors 202 to press the corresponding weighing sensors 202. Further, as shown in FIGS. 3 and 5, the upper cover 201, the middle plate 203, and the lower cover 204 have increasing diameters to form a first step 208 on the edge of the weighing module 2. A second step 14 for matching and engaging with the first step 208 is provided on the edge of the partition 13 in the second cavity 12. Further, as shown in FIG. 4, the weighing module 21, controller 22, communication module 23, power module 24, and wake-up module 25 are embedded in corresponding mounting regions on the lower surface of the middle plate 203.
